Agreement of Fixation Disparity Curve between Two Different Instruments
SIGNIFICANCE
Fixation disparity tests with various characteristics of fusional stimulus are very important for assessment of decompensated heterophoria. The results suggest that there was no reasonable agreement between the fixation disparity curve's parameters of the modified near Mallett unit and the Sheedy disparometer.
PURPOSE
The purpose of this study was to determine the agreement of the fixation disparity curve parameters between the modified near Mallett unit and the Sheedy disparometer in patients with decompensated near heterophoria.
METHODS
A total of 147 young adults (mean age, 22.7 ± 4.8 yea...

Convergence Insufficiency in the Geriatric Population
CONCLUSIONS
The results of the present study showed a high prevalence of convergence insufficiency in the geriatric population. Clinicians should give special attention to this binocular vision disorder in this age group. (Source: Optometry and Vision Science)

A Comparison between Automated Subjective Refraction and Traditional Subjective Refraction in Keratoconus Patients
CONCLUSIONS
The Eye Refract seems to offer similar results compared with the traditional subjective refraction in keratoconus patients not implanted with ICRS. However, some patients could show abnormal measurements, especially those with ICRS, who should be treated with caution in clinical practice. (Source: Optometry and Vision Science)

Personalized Telerehabilitation for a Head-mounted Low Vision Aid: A Randomized Feasibility Study
CONCLUSIONS
The data demonstrated the feasibility of a randomized controlled telerehabilitation study for people with low vision using a head-mounted display. Positive feedback from the participants and the therapist suggests the potential value of this modality for low vision services. (Source: Optometry and Vision Science)

Effect of Hygiene Procedures on Lens Case Contamination with Povidone-Iodine or Multipurpose Disinfecting Solutions
This study compared the ability of two MPDSs, one containing PI and another containing polyaminopropyl biguanide and polyquaternium, to reduce bacterial numbers in solution or adhered to the cases following case hygiene procedures.
METHODS
Bacterial strains (Delftia acidovorans, Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Serratia marcescens, Staphylococcus aureus, and Staphylococcus epidermidis) were exposed to the MPDSs for the recommended disinfection times, and the viable number evaluated according to ISO 14729. Cases were inoculated with bacterial strains and incubated for 24 hours to allow for biofil...

Case Series: Application of Topography-guided Contoura Refractive Surgery in Highly Irregular Cornea
CONCLUSIONS
Therapy for highly irregular corneas includes wavefront-guided surgery, conservative treatment, corneal transplantation, rigid gas-permeable lenses, and so on. In this case series, topography-guided Contoura refractive surgery provided an excellent option for reducing topographic abnormalities and improving vision. (Source: Optometry and Vision Science)

Case Report: Pentosan Polysulfate Sodium Maculopathy Originally Diagnosed as Pattern Macular Dystrophy
CONCLUSIONS
Because toxic maculopathies are an uncommon diagnosis, screening and recognition of PPS maculopathy are critical in the primary eye care setting. Discontinuation of the insulting agent may be necessary to prevent potentially severe and irreversible vision loss in the at-risk population. (Source: Optometry and Vision Science)

Case Report: Management of Refractory Filamentary Keratitis with N-acetylcysteine
CONCLUSIONS
N-acetylcysteine is not commercially available in an ophthalmic solution and must be compounded by a local pharmacist for patient use. Because filamentary keratitis can be challenging to manage because of frequent recurrences, addition of N-acetylcysteine to the treatment regimen should be considered a viable option in refractory cases when other therapies have failed to provide sustained symptomatic relief and resolution of filaments.

Case Report: Unilateral Cranial Nerve IV Palsy Secondary to Trochlear Schwannoma
CONCLUSIONS
Although rare, schwannoma of the fourth cranial nerve should be considered in cases of cranial nerve IV palsies without an obvious etiology. Neuroimaging of the brain and orbits is warranted in cases where more common etiologies have been ruled out or when other cranial nerves and/or the brainstem are involved.

Interpreting Retinal Nerve Fiber Layer Reflectance Defects Based on Presence of Retinal Nerve Fiber Bundles
CONCLUSIONS
Retinal nerve fiber layer reflectance defects, which were associated with deep perimetric defects, usually had a region with absence of fibers on AOSLO images of RNFL. Ability to predict severity of perimetric damage from en face SD-OCT RNFL reflectance images could benefit from quantification that differentiated between absence of fibers and unusual fibers.
